(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to find the concentration of the H_{2}O_{2}that we used

2. Relevant equations

2KMnO_{4}+ 5H_{2}O_{2}+ 3H_{2}SO_{4}→ 2MnSO_{4}+ 5O_{2}+ 8 H_{2}O + K_{2}SO_{4}(not sure if correct)

we got an average of 34.5 ml of titrant, for solution we were adding the titrant to being 5ml of Hydrogen peroxide, and 65 ml of H_{2}SO_{4}

.6 m H_{2}SO_{4}

.050 M KMnO_{4}

? M H_{2}O_{2}(what I am trying to find)

3. The attempt at a solution

.8625 (very high % error, supposed to be .03 If i did it correctly [3 grams per 100ml in a water based solution is .03 right?])

I would like to know what I did wrong, and how i could fix it.

thank you in advance!
